what are the causes of low stomach acid
There are several possible causes of low stomach acid, also known as hypochlorhydria. Here are some of the most common ones:
Age: As we age, the production of stomach acid decreases naturally. This means that older adults are more likely to experience low stomach acid.
Chronic stress: Chronic stress can affect the production of stomach acid by disrupting the balance of hormones and neurotransmitters that regulate digestion.
Acid-reducing medications: Medications such as proton pump inhibitors (PPIs) and histamine receptor antagonists (H2 blockers) can decrease the production of stomach acid.
H. pylori infection: Helicobacter pylori is a type of bacteria that can infect the stomach lining and cause inflammation, which can reduce the production of stomach acid.
Autoimmune conditions: Certain autoimmune conditions, such as pernicious anemia and autoimmune gastritis, can damage the cells in the stomach that produce acid.
Gastric surgery: Some types of gastric surgery, such as gastric bypass and sleeve gastrectomy, can reduce the production of stomach acid.
Diet: A diet high in processed foods, sugar, and carbohydrates, and low in nutrient-dense foods like fruits and vegetables, can contribute to low stomach acid.
It’s important to note that the symptoms of low stomach acid can be similar to those of high stomach acid, so it’s important to work with a healthcare professional to determine the root cause of your symptoms.
